Psychosocial workload combines cognitive, emotional, and interpersonal workload categories, with a job exhibiting low (<2 categories), or high (≥2 categories) number of these categories.
Psychosocial impairment combines cognitive, emotional, and interpersonal impairment categories, with survivors having impairments in low (<2 categories), or high (≥2 categories) number of these categories.
Analyzed using functional impairments, pain, and fatigue at 6 months.
Analyzed using functional impairments, pain, and fatigue at 12 months.
